Different pipes fitting
Extends from OpenHPL.Icons.Fitting (Pipe fitting icon), OpenHPL.Interfaces.TwoContacts (Model of two connectors).
Information
Various possibilities of the fittings for the pipes with different diameters and also the orifices in the pipe. Here, the pressure drop due to these constrictions is defined.

Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Types.Fitting | fit_type | OpenHPL.Types.Fitting.Square | Type of pipe fitting |
| Geometry | |||
| SI.Diameter | D_i | 5.8 | Pipe diameter of the inlet (LHS) |
| SI.Diameter | D_o | 3.3 | Pipe diameter of the outlet (RHS) |
| Modelica.Units.NonSI.Angle_deg | theta | 45 | If Tapered fitting: angle of the tapered reduction/expansion |
| SI.Length | L | 1 | If Thick Orifice: length of the thick orifice, condition L/D_2<=5. If this condition is not satisfied (L is longer) then use Square Reduction followed by Square Expansion |
